Stainless steel flange can be said to be a tool that our families will use, flange is also called flange or flange. The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe. There are holes in the flange and bolts make the two flanges tightly connected. The flange is sealed with a gasket. Flanges are divided into threaded connection (wire connection) flanges and welded flanges.
The basic shape of the stainless steel flange is the same as that of the flat welded flange with neck, that is, there is a bearing hole on the inner hole of the flange, the pipe is inserted into the bearing hole and welded, and a circle of welding seam is welded on the back of the flange. Due to the gap between the stainless steel flange and the caozi, corrosion is easy to occur, and this corrosion can be avoided if a joint is welded inside. The fatigue strength of the socket flange welded on both internal and external sides is 5% larger than that of the flat welded flange and the static strength is the same. The inner diameter of the socket flange should be consistent with the inner diameter of the pipe. The socket flange is only suitable for the use of the pipe with the nominal diameter below 150. Common materials of socket stainless steel flange include: 201 304 316 304L 316.
Welded threaded stainless steel flanges are forged and can also be threaded or welded. It is composed of a pair of threaded flanges, a gasket and several bolts and nuts. The gasket is placed between the sealing surface of the two flanges, and after tightening the nut, the specific pressure on the surface of the gasket will be deformed after reaching a certain value, and the uneven part of the sealing surface will be filled to make the connection tight and not leak. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flange connection is an important connection mode in pipeline construction.
Threaded stainless steel flange connection is easy to use and can withstand greater pressure. Flange connections are widely used in industrial pipelines. Generally speaking, the role of the welded socket stainless steel flange is to make the pipe joint fixed and sealed. The stainless steel thread flange connects the pipeline and maintains the sealing performance of the pipeline, which is easy to replace a certain section of the pipeline, easy to disassemble and check the pipeline, and easy to close a certain section of the pipeline.
